TO ALL WHOM IT MAY CONCERN;

p Be it known that I, GEORGE HOWELL, of the city and county or,Philofleiphia, and State of Pennsylvania, have invented a new andimprovedMode of Filling Marshes, 85o.; and I do hereby declare that thefolloviing is afnll and exact description thereof, reference being hadto the accompanying drawings and to the letters oi' reference markedthereon.

My invention is :in improvementon my mode of filling marshes, A35e.,patented November 12, 1857, und

inninly consists, iirst, in anV excavating and pumping-apparatus,combined 'with o. scoxv or boot, beneuth which it is plnced foriheremovel of the mud oreorth from the hed o the river or other sheet ofwater; the'saidieppzr rntus being submerged and elevated et pleasure bymeans ot' vertical screws operated by ineens of ageored connection witha driving-shaft of esteem-engine. In the second place, the improvementconsists in o. novel mode of detcrminingthc'proper depth to submerge theapparatus; und, in the third place, in a mode of holding it in itsoltitudinol position. The construction and arrangement of the appara-tuswill be understood hy the following description. In the accompanyingdrnwings, which make a part of this specification- Figui-e1 is alplon ofthe apparatus, in combination with a. scow.

'Figure 2 is a side elevation of the same.

Figure 3 is a. view of the excavating-caso A from beneath.

Figure 4 isv on end view of one of the shafts B, providednith stirrersC.

Figure 5 is e side view of one of the gripes W.

Figure 6 is an isometrical view of the gauge S.

Figure 7 is afvievv of the geared lever Q, and parts in connection.

Figure 8 is a front view of the same.

Likeletters in all the iigur'es indicate'the same parts.

A is o. cose, containing o series of revolving shztftsB, which areprovided with stirrers C for loosening the mud or earth und mixing itVwiththe water it underlies, so as 'to bring it to the properconsistency to be sucked up and removed by the pump D, which is securedto the suction-pipe E. Spid pipe has n nnge, a, which is bolted to theupper suri'ace of the cose A,-so as to rise and follwith it in itsadjustment. The shoi'ts B have wheels b, which gear intoI the pinions con'the longitudinal .shaft F, and themotion is given to said shaft bymeans of its connections with the vertical shuft G, there being 'obevel-pinion, el, on the lower end of saidshoft. There is a pinion, d1,on the upper'end of the shaft, which gears into the wheelv e, on oneend-of4 the shaft H,

whichpasses through the body of the pump D, and has on its other end a.spur- Wheel-,f, which gears into the.

pinion f -on the short shaft H'.. The said shaft has n connection withthe counter-shaft I in the frame J, by means of the belt g and pulleys7i z.

' The counter-shaft is driven by the shaft K of the engine, which inpractice is placed on boardV thc s-coiv A', there beingra pulley, z', onthe shaft K, und i on the counter-shaft I, cpnnectedy bythe belt j.

The pump is rotated by means of the belt k, which connects the pulleylofpump and Z' ofthe counter-shai`t. The framed', which supports thecounter-shaft', .turns partially onthe drivingshoi't Krto provideforltighL ening the belts, there being coupling-rods M and M',connecting witlr scour A and frame J, as seen iu iig. 1; The case A issubmerged and elevated by means of the vertical screnwrods N, whichoreconnected with it :xt their loner ends, as seen in iig. f?. The upperends of the rods are provided with bevel-Wheels o, that Ageur into thepinions o. on the shafts O, O1, and O zfsothet by turning one of saidshafts the same motion is 'given to thefour vertical screw-rodsN, whichmotion is`given by mea-ns of the beltPfpulley q, on the driving-shaft,and q on the short shaft L, on the shifting-lever Q, and uprightprojection r, on one Voi' the pedestuls R. On the other end of saidshaft L there is a spur-pinion, s, which geors' into the pinions s* :inde? on-the pronged end of the lever. When the screw-rods N are not to beopernted,"the lever is in the position seen in figs. 7 and' 8, sheet No.2, which. keeps both of the pinions s and e2 out of gear with thc'wheelt on the shaft-O1; but when motion is to be gvento the rods, for theelevation or depression oi the case A, one ofthe pini'onsfis broughtinto gear with the wheel. The reverse motion is given by reversing thelever. 'There is a milled heed, u,for

fastening the lever against the projection r of the pedestal R, thescrew-stem v of the head playing in the eccentric slot w of theprojection. i

The scow has an opening in its bottom large enoughto receive the ease Awhen in shallow water. There is a gauge-rod, S, which is provided witha. foot, S', that sinks into the mud and determines the depth, slightlyyresting on the end of the screw-rod N when the case is submerged theproper depth.

There are chains T 'l over the pulleys UU inthe standards V V, 'whichare provided with weights :c to keep them tight. The lower ends ofthechains branch oif to each side of the case A, and are fastened thereto.Whcn the case is at its proper depth, the gripes WNV-are drawn inwardsin the standards by means of hand-wheels X X v on the screw-Shanks ofthe gripes to' confine the chain against the standards,pand thus securesaid case in its position.

The stirrcrs C are made of Hat springs of steel, as represented in figs.3 and 4, and have a bent form, so as to cause them to readily springwhen they strike any unyielding object, to keep them from breaking.Otherwise the construction'and arrangement of the stirrersare the sameas represented in my patent, dated November 12, 1867.

l` attach a hose or tube to the flange y ot'A the pump l) for-`conveying the mud to its destination.

'.lhere arelinks Y, Y, and Y2, which connect the case A and Vscow A atside to give a parallel motion und firmness to thc-former, to take thestrain oil' the rodN. There are also guiding vertical rods Z Z, thelower ends of which are secured to each end of the case, and their upperends pass through the scow, as seen in figs. 1 and 2. 4

It will be seen that when the case is loweredgto its proper depth, andthe stirrer-shafts are revolved rapidly by means of their connectionwitlrthe driving-shaft'K, through the gearing above described, the mudand Water become thoroughly mixed, andare sucked up .by the pump D andforced through the hoseor tube.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination and arrangement of the case A with a scow or boat bymeans of the vertical serewrods N, wheels o, pinions o', and`shafts O,O, and O2, the said parts being arranged and operating substantially asdescribed. y

2. '.Lhc combinatioirof the links Y,Y, and Yz with the case A and scowA', for giving a parallel motion to lthe'former, substantially asdescribed.

3. The combination of the vertical rods Z Z with the case Aand scow A',substantially as described.

4. The geared shifting-lever Q, arranged and operating in relation tothe driving-shaft K and shaft O, substantiallyin the manner and for thepurpose specified.

5. The combination of the chains Tpulleys U, standards V, and gripes W,with the case A and scow A', for 'holding the case in its altitudinalposition, substantially as described.

6. The combination of the coupling-rods M and M' with the case Aand'scow A', substantially as described and for the purpose specified.
